Result Description / Recommendation
None ABORT Could not allocate the necessary system resources to run this test. For
example, maintenance could be running on the Tone Detector circuit and it is
using the CPTRs.
1115 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 3 times.
Any FAIL The error code indicates the number of bad time slots that were detected. The
cause of this failure is most likely due to a bad port circuit pack and not the
TDM bus itself.
1. Execute the command again.
2. If the error persists, check the Error and Alarm Logs for alarms, on the port
network where the faulted TDM bus resides, on port circuit packs from the
NPE Crosstalk test. Also check for EXP-INTF alarms associated with error
type 1537.
3. Refer to the appropriate circuit pack’s documentation to clear the circuit
pack’s problem.
4. Test the TDM bus again. If the error continues, see ‘‘TDM-Bus Fault
Detection and Isolation’’.
PASS The success of this test indicates every idle time slot that is supposed to be idle
is indeed idle. There is no noise on any of the idle time slots.
